AB-QM 4.0 / AB-QM Pressure Independent Control Valves (PICV) DN 15-250

The AB‑QM valve equipped with an actuator is a control valve with full authority and an automatic balancing func tion / flow limitation. Typical applications are: Temperature control with permanent automatic balancing on terminal units (chillers, air‑handling units, fan coils, induction units, radiation panels and heat exchangers). Without an actuator is a flow limiter e.g for one‑pipe systems.

Description

The Danfoss AB-QM is a Pressure Independent Control Valve (PICV) that combines high accuracy and durability with market leading user-friendliness. The design of the AB-QM is fully geared towards making your project run on time and on budget while delivering the most efficient HVAC system. Pressure independent valves are control valves with an automatic balancing function. An in-built pressure controller keeps a constant differential pressure over the control valve, ensuring full authority and automatic flow limitation. By combining two functions in one, control and automatic hydronic balance, Danfoss PICVs provide a cost-efficient solution for the challenges faced by forward-looking designers of HVAC systems.

The Danfoss AB-QM delivers the lowest total cost of ownership because:

• Precise flow limitation ensures always the right flow at the right time, ensuring minimized pumping energy

• Full range from DN15 to DN250 for flows up to 407 m3/h

• Available with internal and external thread for universal applicability

• Danfoss’ durability test ensures the AB-QM has best-in-class resistance to scaling and clogging

• Easy troubleshooting because of the always visible setting and the ability to measure flow through test plugs

• Minimum hysteresis for stable and precise temperature control

• Future-ready with a range of smart actuators, ready for data driven and optimized HVAC 4.0

Factory se tting of the valve is done at no minal setting range.

Regardless o f the setting, the valve can mo dulate below 1 % of set flow.

When set above 100 % , minimum starting pressu re needed is higher, see figu res in the ().
